The Facebook co-founder and CEO is now the father of a baby girl named August and he shared a photo of him, Priscilla, and their daughter Max with the newborn.

“Priscilla and I are so happy to welcome our daughter August! We wrote her a letter about the world we hope she grows up in, and also hoping she doesn’t grow up too fast,” Mark announced on his Facebook page.

“Childhood is magical. You only get to be a child once, so don’t spend it worrying too much about the future. You’ve got us for that, and we’ll do everything we possibly can to make sure the world is a better place for you and all children in your generation,” Mark and Priscilla wrote in the letter to their child. “August, we love you so much and we’re so excited to go on this adventure with you. We wish you a life of joy, love and the same hope you give us.”

Mark Zuckerberg, the founder and CEO of the social networking service, released a statement in the form of a post on Tuesday (June 27) to celebrate the occasion.

“As of this morning, the Facebook community is now officially 2 billion people!” he wrote. “We’re making progress connecting the world, and now let’s bring the world closer together. It’s an honor to be on this journey with you.”

Mark Zuckerberg very briefly addressed the murder who killed 74-year-old Robert Godwin Sr. in a Facebook video over the weekend.

“Our hearts go out to the family and friends of Robert Godwin Sr., and we have a lot of work – and we will keep doing all we can to prevent tragedies like this from happening,” Marktold the crowd at his annual F8 Facebook Developers’ Conference on Tuesday (April 18) in San Jose, Calif.
